I teach physics at Fullerton College, a community college in Southern California. I have an undergrad degree in math and physics from Berkeley and a PhD in physics from Yale. Back when I was doing research, my field was experimental low-energy nuclear physics.

Can general relativity be completely described as a field in a flat space? The paper is here: adsabs.harvard.edu/abs/2013IJAA....3....8L From a casual examination, it seems like a rehash of Deser's ideas from decades ago. The journal is a SCIRP journal. SCIRP is an infamous predatory publisher: scienceblogs.com/aardvarchaeology/2012/04/12/… |

Precision of Coulomb's law @firtree: I don't think it's the same question, and I don't think the answer addresses this question. This one is about small corrections under normal conditions. The other is about conditions under which it becomes a poor approximation. |

Precision of Coulomb's law The 2013 edition of Purcell and Morin still gives a reference to the 1971 Williams paper, so I believe that's still the tightest bound by that technique. |

What is the physical meaning of fact, that Reissner-Nordstrom black hole is thermodynamically unstable? You can edit the question to include the reference. |

How reliant is the Solar System on being exactly the way it is? Googling on "lyapunov exponent solar system" (without the quotes) gives a whole bunch of relevant papers. |

How reliant is the Solar System on being exactly the way it is? The revision is an improvement. Removed my downvote. |

Would this be a metric? @JerrySchirmer: I don't necessarily disagree with your comment, but I would put it a different way. For example, in the limit $c\rightarrow\infty$, you can in some sense recover Newtonian physics from relativity. In this limit the metric becomes degenerate. The way I would express it is that Newtonian spacetime simply doesn't have a metric. What Newtonian physics has is a spatial metric. |
